DETAILED DESCRIPTION OF EMBODIMENTS

Embodiments of the invention will now be described with reference to theaccompanying figures. The terminology used in the description presentedherein is not intended to be interpreted in any limited or restrictivemanner, simply because it is being utilized in conjunction with adetailed description of certain specific embodiments of the invention.Furthermore, embodiments of the invention may comprise several novelfeatures, no single one of which is solely responsible for its desirableattributes or which is essential to practicing the inventions hereindescribed.

As used herein, the terms “golf GPS device” and “device” may be usedinterchangeably. Further, as used herein, the terms “player,” “user,”and “player-user” may be used interchangeably.

Golf GPS Device with Clip

A golf GPS device including an integrated clip is typically clipped witha golfer's headwear or waist belt. In a golf GPS device including adisplay screen, when the device is clipped with the golfer's headwearsuch as a cap or hat, it would be difficult for the golfer to read theinformation displayed on the display screen because the display screenwould likely face away from the golfer's eyes. In such a situation, thebattery power of the golf GPS device will be wasted for the time whenthe golf GPS device is clipped with golfer's headwear. It would bebetter to turn off the display screen when the golf GPS devicedetermines that it is clipped with the golfer's headwear.

Also, when the golf GPS device is clipped with the golfer's waist belt,it would be difficult for the golfer to read information displayed onthe display screen because the information would be upside down for thegolfer's eyes. It would be helpful for the golfer to read theinformation if the information displayed on the display screen isdisplayed upside down when the golf GPS device determines that it isclipped with the golfer's waist belt.

Further, some golf GPS devices with an audio module that generates thesound of certain information about the golf courses and golf plays, suchas the distance of the golf GPS device to the green of the hole thegolfer is playing. Sometimes such a golf GPS device is carried near thegolfer's ears. In other times such a golf GPS device is carried somehowaway from the golfer's ears, for example, when the GPS device is kept orclipped with golfer's waist belt. In such a situation, it would behelpful that the golf GPS device turns off the volume of the sound whenit determines that it is clipped with the golfer's waist belt.

General Structure and Operation

In embodiments, a portable information processing and viewing device isprovided. Referring to FIGS. 1 and 7, the device includes a body housinga GPS receiver 302, a memory 306, one or more processors 300 and a userinterface, the body comprising a front surface and a rear surface. TheGPS receiver receives GPS information transmitted from satellites. Thememory stores map information or map data 308 of golf courses, each ofwhich includes at least one hole and at least one feature on the hole.The one or more processors determine a distance between the device and alocation on a golf course stored in the memory as part of the mapinformation. The user interface provides a user with the determineddistance. The user interface includes a display screen 304 on the frontsurface and a speaker 310 housed in the body.

In embodiments, the device further includes a clip integrated with thebody. The clip includes a spring plate that faces the rear surface ofthe body of the GPS device. In one embodiment, the clip may bedisintegrated from the GPS device. Based on input from one or moresensors or sensing elements, the one or more processors furtherdetermine whether something is gripped between the spring plate and therear surface by spring action of the spring plate. When determining thatno object is gripped between the spring plate and the rear surface, thedisplay screen displays the determined distance in a first orientation,and the speaker generates sound at a first volume of the determineddistance in response to a user request.

In embodiments, upon determining that an object is gripped between thespring plate and the rear surface by spring action of the spring plate,the one or more processors cause the user interface to operate in a clipmode, which includes one or more selected from the group consisting ofi) not displaying the determined distance on the display screen, ii)displaying the determined distance on the display screen in a secondorientation different from the first orientation, and iii) upon a userrequest, generating sound of the determined distance at a second volumehigher than the first volume. Upon determining that the object isungripped between the spring plate and the rear surface (i.e., theobject is disengaged or removed from the spring plate of the clip) theone or more processors cause the user interface to return to theprevious state of displaying the determined distance in the firstorientation and generating sound at the first volume.

Golf GPS Device with Automatic Hole Recognition

Many golf GPS devices now have the feature of automatic holerecognition, which is to determine the particular hole in which the GPSdevice is located as the user travels along the golf course as the golfplay proceeds. For example, the automatic hole recognition featuredetermines if the location of the GPS device is within a predeterminedarea or boundary of a particular one of the plurality of holes of golfcourse. The golf GPS device will include map information of the golfcourse, which includes the predetermined area or the boundary of such anareas for the automatic hole recognition feature. In such a device, whenthe user or golfer travels from one hole to another, e.g., from apredetermined area of one hole to a predetermined area of the otherhole, the GPS device will automatically recognize the movement of thegolfer from one hole to the other.

Golf GPS Device with Playing Hole Determination

During a play in a hole, sometimes golfers travel to another hole beforefinishing the play in the particular hole for various reasons. Forexample, a golfer playing in one hole (e.g., Hole 4) hits by mistake herball to an area of another hole (e.g., Hole 11) that is adjacent to thehole (Hole 4) she is playing. Then, the golfer travels to the other hole(Hole 11) to complete her play for the playing hole (Hole 4). When thegolfer uses a golf GPS device with the automatic hole recognitionfeature, the GPS device will recognize the other hole (Hole 11) when thegolfer travels from her playing hole (Hole 4) to the hole in which herball is located (Hole 11), e.g., when her golf GPS device enters apredetermined area of the other hole (Hole 11).

As the golf GPS device recognizes the other hole (Hole 11), the devicewill automatically compute and display on its screen the distancebetween the device and the green (or a position on the green) of theother hole (Hole 11). Sometimes this automatic actions of the device mayconfuse the golfer as the information displayed on the screen isdifferent from what the golfer will likely look for, i.e., the distancebetween the device and the green (or a portion of the green) of theplaying hole (Hole 4). In case the golfer recognizes that the displayedinformation is not what she is looking for, then the golfer would needto override what the device has done by changing the hole (Hole 11) thatthe device automatically recognized to the hole (Hole 4) that the golferis playing. To do that the golfer should know how to change the holethat she is playing in the device. Typically such a change would requiremultiple actions of the golfer such as changing the currently displayedhole to the next hole (either immediately previous or subsequent hole)of the golf course until the golfer reaches the playing hole. When theplaying hole is Hole 4 and the currently displayed hole is Hole 11, thegolfer may have to transition the hole from Hole 11 to Hole 10, then toHole 9 . . . until Hole 4 is displayed.

In embodiments of the invention, when the golf GPS automaticallyrecognizes the change of holes, then the device automatically determineswhether the new hole is immediately subsequent to the previouslydisplayed hole. Further the golf GPS device provides a user interface inwhich two or more hole numbers are displayed for selection of thegolfer. Then, the golfer can select the appropriate hole based on thestatus of the golf game. In other embodiments, the golf GPS device isequipped with a physical or electronic hot key for returning to thepreviously played hole when the device recognizes the hole change andhas displayed information of the new hole. When the golfer hits the hotkey, then the golf GPS device displays the information of the previouslyplayed hole.

Predetermined Area

The predetermined area or boundary for automatic hole recognitionfeature can vary from hole to hole. In embodiments, the predeterminedarea covers only a portion of a particular hole or covers substantiallyall area of a particular hole. In some embodiments, the predeterminedarea covers certain portions of a particular hole in which typicallygolfers travel when advancing to the next hole during golf plays. Insome embodiments, the predetermined area of a hole covers the tee-offarea of the hole. In some embodiments, one hole may have more than onepredetermined area.

Referring to FIG. 10, holes 400and 450 comprises a greens 404 and 454 and a tee-off areas 402 and 452.Map information of each hole comprises locational information of thegreen 404 or 454 and locational information of the tee-off area 402 or452 and the hole number pre-assigned to that hole. The feature of thefirst hole 400 comprises a position of or associated with the green 404of the first hole 402, wherein the position of or associated with thegreen 404 is predetermined and included in the map information of thefirst hole 400 or chosen by a predetermined algorithm at the time ofcomputing the first distance.

In embodiments, each hole map information comprises a predetermined areadefined with a boundary line or boundary lines on a map of that hole 400or 450. The boundary line or lines of the predetermined area does notaccurately follow the boundary of the hole as published by the golfcourse. The predetermined area is used for determining whether thedevice is located within the hole such that when the device is locatedwithin the predetermined area of the second hole, then the processordetermine that the device is located in the second hole 450.

In embodiments, the predetermined area of each hole does not encompass aportion of the hole. The processor may determine that the device remainslocated in the first hole 400 once the device is within thepredetermined area of the first hole 400 and leaves the predeterminedarea of the first hole 400 as long as the device does not enter thepredetermined area of another hole, for example hole 450.

In embodiments, the processor may determine that the device has movedfrom the first hole 400 to the second hole 450, when the device travelsfrom a location within the predetermined area of the first hole tooutside the predetermined area of the first hole, and then enters thepredetermined area of the second hole.

Unintended Playing Hole Change

In some situations, a player, while playing on hole X (400 in FIG. 10),accidently hits the ball to the course of hole Y (450 in FIG. 10) beforecompleting playing on hole X. In certain situations, hole Y is thesubsequent hole after hole X. However in other situations, hole Y issimply a neighboring hole or a hole that is close to hole X and not thesubsequent hole. In some embodiments, once the player moves to thelocation of the ball on hole Y, the golf GPS device will automaticallyrecognize that the device is now located on the course of hole Y. Thegolf GPS device will further begin to determine distances between thedevice's current location on hole Y and various features along hole Y,such as those discussed above. However, because the player has not yetcompleted hole X, the player would rather want to know distances betweenthe player (or the device) and various features of hole X.

In an embodiment, the player-user can manually select hole X on thedevice as to instruct the device to determine and report distances fromthe device to various features of hole X. However, this can be timeconsuming and/or inconvenient depending on the manual selection system,especially if the user has to scroll through a list of a plurality ofholes to select hole X.

User Selection of Playing Hole

Referring to FIGS. 9 and 10, in embodiments, in order to allow a user toselect hole X on the device, the processor 300 of the golf GPS device isconfigured to repeatedly determine in which one of the plurality ofholes the device is located, and to determine if the device has movedfrom a first one 400 of the plurality of holes to a second one 450 ofthe plurality of holes. Once determined that the device has moved fromthe first hole 400 to the second hole 450, the processor determineswhether or not the second hole is immediately subsequent to the firsthole in terms of the pre-assigned hole numbers of the first and secondholes in the golf course. When determined that the second hole 450 isnot immediately subsequent to the first hole 400 in terms of thepre-assigned hole numbers of the first and second holes in the golfcourse, the processor causes to display for selection by a user the holenumbers of the first and second holes on the display screen as shown inFIG. 7. Upon the user's selection of the hole number of the first hole400, the processor computes a distance between the device and a feature404 of the first hole 400 and causes to display the computed distance onthe display screen and the hole number of the first hole 400 asillustrated in FIG. 8.

When the user select the second hole 450, the processor computes adistance between the device and a feature 454 of the second hole 450 andcauses to display the computed distance on the display screen and thehole number of the second hole 450.

Automatic Change to Next Hole

With continuous reference to FIGS. 9 and 10, when determined that thesecond hole 450 is immediately subsequent to the first hole, theprocessor determines if the device has stayed within a predeterminedzone 408 of the first hole 400 before moving to the second hole 450.When determined that the device has not stayed within the predeterminedzone 408, the processor computes the first distance between the deviceand the feature, for example, the green 404 of the first hole 400 andcauses to display the computed first distance on the display screen.

For this, the map information of the holes 400 and 450 include thepredetermined zones 408 and 458, which comprise an arbitrarily definedarea on a map of the corresponding hole. The areas encompass one or morefeatures of hole, for example, at least part of the green 404, a golfcart paths 406 and 456 next to the greens 404, 454, an area adjacent thegreen 404, and an area surrounding the green 404. The zone 408 includesthe green 404. Alternatively, the zone 458 exclude the green 454 whilesurrounding the green 454. In embodiments, the predetermined zones 408and 458 do not include tee-off areas 402 and 452.

In embodiments, when determined that the second hole is immediatelysubsequent to the first hole 400, the processor determines if the devicehas stayed within a predetermined zone 404 of the first hole for apredetermined period or longer before moving to the second hole 450.When determined that the device has stayed within the predetermined zone404 for the predetermined period or longer, only then the processorcomputes a distance between the device and a feature 454 of the secondhole 450 and causes to display the computed distance on the displayscreen.

Hot Key Function

In some embodiments, the golf GPS device includes a hot key or someother unique input that the user can select or otherwise input toaccelerate this process. Upon receiving input to trigger the hot keyfeature, the golf GPS device can automatically identify the immediatelyprevious hole where the device was located without having to go throughother holes intervening between holes X and Y in order. The golf GPSdevice can further determine and convey to the user information relatedto features of the immediately previous hole, such as but not limited todistances between the device's current location to various features ofthe immediately previous hole.

In certain embodiments, upon receiving such unique input, the golf GPSdevice determines whether the immediately previous hole was completed ornot. In order to do so, in some embodiments, the device can determineone or more of whether the device was within a certain distance of thehole cup of the immediately previous hole and whether the device wasever located on the green of the immediately previous hole. If thedevice determines that it was, then in certain embodiments, the deviceconfirms that the player accidently moved to another hole beforecompleting the previous hole.

This hot key function is not limited to golf GPS devices of anyparticular type. Rather, the hot key function may be incorporated intoany type of golf GPS device. For example, any of the golf GPS devicesillustrated in FIG. 5B 502, 504, 506, 508 can comprise the hot keyfunction described herein.

Hot Key Input

In an embodiment, the hot key is a single button that is located on thefront surface, the back surface, or the circumferential surfaces. Inanother embodiment, the hot key is a plurality of buttons that a userhas to press or otherwise select. Such plurality of buttons can belocated on the front surface, the back surface, or the circumferentialsurfaces. In certain embodiments, individual buttons of the plurality ofbuttons can be located on different surfaces among the front surface,the back surface, and the circumferential surfaces. For example, in anembodiment, a user can press the main button 104 and the position markbutton 108 together at the same time to trigger the hot key function.

Further, in an embodiment, the hot key is not a physical button but is aunique pressing pattern on a touchscreen input located on the golf GPSdevice. In some embodiments, the display itself is a touchscreen uponwhich a user can input the unique pressing pattern to trigger the hotkey. In certain embodiments, the unique pressing pattern can be a uniquesliding motion, a unique tapping motion, or a unique combination of anytouch screen input.

No Hot Key Input

In an embodiment, the golf GPS device does not comprise a hot key but isconfigured to automatically perform the hot key function underparticular circumstances. For example, in some embodiments, when thegolf GPS device detects that the location of the device has moved from apoint on hole X to hole Y, the golf GPS device is configured todetermine whether hole Y is the immediately subsequent hole in order. Insome embodiments, if hole Y is not the immediately subsequent hole inorder, then the hot key function is automatically triggered. In certainembodiments, if hole Y is the immediately subsequent hole in order, thenthe hot key function is not triggered.

In certain embodiments, when the golf GPS device detects that thelocation of the device has moved from a point on hole X to hole Y, thegolf GPS device is configured to determine whether hole X was completedby one or more methods described above. In some embodiments, if the golfGPS device determines that hole X was not completed, then the hot keyfunction is automatically triggered. In certain embodiments, if the golfGPS device determines that hole X was completed, then the hot keyfunction is not triggered.

In some embodiments, the hot key function is automatically triggeredwhen the golf GPS device determines that hole Y is not the immediatelysubsequent hole to hole X in order and that hole X was not completed. Inother embodiments, the hot key function is automatically triggered whenthe golf GPS device determines that hole Y is not the immediatelysubsequent hole to hole X in order or that hole X was not completed.

Dynamic Green View

In an embodiment, the golf GPS device displays a view of the green ofthe hole where the device is currently located. In general, depending onthe location of the player relative to the green, the view of the greenas seen from the player's point of view will be different. In someembodiments, the golf GPS device automatically determines the directionfrom which the player will be approaching the green and tilts thedisplay of the green accordingly on the display. In other words, thegolf GPS device displays the view of the green as seen from the player'slocation.
